Why would two Eastern European meatboys want to whack an innocent cab driver? That's the question that occurs to Gilrein as Raban and Blumfeld press the gun barrel into his mouth. Does it have something to do with the ritual death-by-flensing of Leo Tani? Or does the answer involve Gilrein's ex-lover, now working as a librarian for a bibliomaniac gangster? Or maybe the whole thing has something to do with the Inspector, inventor of the notorious Methodology? So many questions and more in the fourth book in the Quinsigamond Quintet.
